This method is effective for dialing in a camshaft where power is a main concern. Remove the bolts in the driver’s side valve cover using a socket. Remove the valve cover. Remove the distributor cap if applicable, using a screwdriver. Rotate the engine clockwise using a socket and ratchet on the crankshaft bolt.
